If you can get the correct replacement it should just slide in under a spring steel clip

    First you need to find where is the dam batery.

  • dodgese May 20, 2011

    The CMOS clock battery is a cr 1220 lithium battery. The case has to be opened, the soundboard removed to gain access to it. The rechargeable battery to maintain hibernation is located in the middle where the LCD screen and the case meet, behind the LCD video connector.

Purchased a Compaq Armada 7800 from a pawn shop. The power cord plugs directly into the back of the machine with no adapter. Does this machine have a built in adapter? Does it have a battery? I dont...


Hi. Yes, it has an "Integrated AC Adapter for less bulky transportation; 8-foot power cord included"

It also has a Li-ion Battery Pack on the left side which provides over 2 hours of battery life - if its OEM, but there are higher capacity batteries you can get for it at amazon or eBay .

This Link will take you to HP's page for more data and diagrams on your machine.

Not sure I bought a used compaq armada e 500. it


Maybe,however there are a few things you can do to stablize the computer.First of all the system fan and the vents needs to be cleaned,secondly you need to put thermal grease between the processor and the heat sink.This should stop the computer from shutting down.As for the system time you can check the cmos battery or change it.
Good luck

My compaq armada 7800 display is very poor


It's probably the lcd, but it could also be the GPU, lcd cable and or the motherboard.

You'll have to have a local tech check it out to verify the problem.

Crashed HD and now way to get to BIOS or BOOT SEQ.


When you power-on the computer, does anything display, such as the amount of RAM, or "press DEL to enter BIOS setup"?

If not, then you have a hardware-problem with your computer;
the "good-news" is that the data on your hard-drive is OK.
If you connect the hard-drive to another computer, you can "rescue" your data-files.

The screen on my compaq armada is blank. i can


The display panel itself is probably fine, but its backlight isn't working. Without the backlight you can't see the display. There's a small circuit board called the inverter inside the display that provides power for the backlight.

It's pretty easy to replace the inverter. You need to take out whatever screws are holding the front half of the display to the back and remove the front. The inverter is at the bottom of the display, held in by a couple of screws. A couple of cables plug into it.

Here is a place that claims they have the inverter in stock for $7.39. That is one fantastic price! Get one of those and a set of miniature Phillips screwdrivers and you'll be able to fix this yourself.

My laptop compaq armada1700 ask me power-on password what can i do?


Follow the instructions of the service manual for the Armada 1700 (you need to have some skills):

2.2 Clearing Passwords
The power-on password prevents use of the computer until the password is entered. The setup password prevents unauthorized changes to Computer Setup. To clear the passwords, you must remove all power from the system board. If you do not know the passwords, use the following procedure to clear the password:

1. Remove all battery packs from the battery bay and MultiBay, if applicable.
2. Disconnect the AC power.
3. Remove the real-time clock battery.
4. Wait five minutes.
5. Reconnect the AC power.
6. Restart the computer. During Power-On Self Test (POST, a "162 System Options not set" message appears.
7. Shut down the computer, then disconnect AC power again.
8. Replace the real-time clock battery.
9. Install the battery pack(s).
10.Proceed with the troubleshooting procedures.

Point 10 means you need to do the setup via disquette to set the date and time again, to avoid the "162 system option not set" message of the POST.
